An air-standard dual cycle has a compression ratio of 16. At the beginning of compression, the pressure and temperature are 100kPa and 294K respectively. Total heat addition to Dual cycle is 430kJ per kg. Heat addition at constant volume to the cycle is 35% of the total heat added, followed by heat addition at constant pressure which is 65% of the heat added to the cycle. Take Cp=1.005kJ/kgK,Cv=0.7178kJ/kgK, and =1.4 Make a P-V sketches [2 marks] and determine the following i. the heat added during the constant volume process [1 mark] ii. the heat added during constant pressure process [1 mark] iii. the temperature and pressure at end of compression process [1.5, 1.5 marks] iv. the temperature at end of the constant volume process [2 marks] v. the pressure at end of the constant volume process [2 marks] vi. the temperature at end of the constant pressure process 2 marks] vii. the temperature at the end of expansion process 2 marks] viii. the heat rejected by cycle [2 marks] ix. the net work done [1 mark] x. the thermal efficiency.
